Hi everyone:

I would like to verify the relationship between F and chi2. But it is found that they are not equal, which step am I doing wrong?

Thanks

Array

Code:
scalar chi2_nu = invchi2tail(60,0.05)
scalar chi2_de = invchi2tail(120,0.05)
scalar numerator= chi2_nu/60

scalar   denominator = chi2_de/120
dis  numerator/denominator
dis invFtail(60,120,0.05)
